gBallBaseLoc = (200, 300);  
gGameRect = (0, 0, 300, 400);

the code above is said to set the boundary for the movie clip…  
i tried it following a tutorial for collision detection but the boundary seems endless…meaning not working…  
is there any other way to set the boundary ?  
I’m need the steps…my actionscript is lousy…  
Please please please help…:\*(
